Hello,

Sorry, I've mistaken what references you pointed the projects to. Based on your description, I changed all references to use the ones from the "references" folder and I was able to build the solution successfully. Please, check the attached image. Have any other changes been made to the projects/solution apart from the references redirection? I'll appreciate any additional information on the environment you might provide, so I can investigate the issue further.

Looking forward to hearing from you.

So even though you have the dll in the reference folder, it still won't work unless you install the 16.1?
